=head1 NAME

    AMF::Perl::IO::Serializer

=head1 DESCRIPTION    

    Class used to convert physical perl objects into binary data.

=head1 CHANGES

=head2 Sun May 23 12:35:19 EDT 2004

=item Changed deduceType() to return the value too, as it may be changed inside, and to 
handle empty string ('') as a string.

=head2 Wed Apr 14 11:06:28 EDT 2004

=item Made basic data type determination work for both scalars and scalarrefs.

=item Now we check if we are sending a recordset and setting column types accordingly.

=head2 Sat Mar 13 16:25:00 EST 2004

=item Patch from Tilghman Lesher that detects numbers and dates in strings
and sets return type accordingly.

=item Patch from Kostas Chatzikokolakis handling encoding and sending null value.

=head2 Sun May 11 16:43:05 EDT 2003

=item Changed writeData to set type to "NULL" when the incoming data is undef. Previously
it became a String, just like other scalars.

=item Changed PHP's writeRecordset to a generic writeAMFObject. Verified Recordset support.

=head2 Sun Mar  9 18:20:16 EST 2003

=item Function writeObject should return the same as writeHash. This assumes that all meaningful data
are stored as hash keys.
